Picaxe 08M tone signal generator

VK4ADC is an Australian amateur radio operator whose on-air activities include weak signal/microwave work. As such, he needed a reliable tone generator to modulate his transmitted RF carrier to permit receiving stations to peak their station’s antenna for maximum signal. So he decided to design his own multi-function tone generator around the Picaxe 08-M. Accustomed […]

PICAXE-08 raincounter

eclectica has posted a circuit for a PICAXE-enabled raincounter. The device employs a 1mm/pulse rain gauge to measure rainfall. Pulses from the gauge’s internal reed switch are read by the PICAXE-08 MCU, which in turn stores the running count in EEPROM and displays the resulting measurement on a serial LCD readout. While the exact type […]

$5.00 simple oscilloscope using Picaxe and VB

Patrick Cambria posts this simple oscilloscope project using a Picaxe-08M microcontroller and a potentiometer. The Picaxe is programmed in BASIC and the entire MCU program follows: main: READADC10 1,B0 SERTXD(#B0,10) goto main The output from a potentiometer voltage divider is fed into an ADC pin of a PICAXE 08M then serially transmitted to a Serial […]

The $5 Picaxe Beatbox

Corticalcafe has posted a project for an audio record and repeat device using a Picaxe-08M microcontroller, piezo speaker, and a handful of resistors. The Beatbox uses LDRs shielded inside nuts to sense the input “drumbeats”! When powered up the LED indicator lights and the circuit senses about 5 seconds of input beats. After the maximum […]
